Chlorophyta or Prasinophyta is a taxon of green algae informally called chlorophytes. Charophycean algae exhibit a haplontic life cycle where the only diploid cell is the zygote that then undergoes meiosis to produce haploid spores (e.g.,). majority haploid, few alt. In older classification systems, it refers to a highly paraphyletic group of all the green algae within the green plants and thus includes about 7,000 species of mostly aquatic photosynthetic eukaryotic … Sexual reproduction can be isogamous, anisogamous, or oogamous. Sea lettuce, (genus Ulva), genus of green algae (family Ulvaceae) usually found growing on rocky shores of seas and oceans around the world. Asexual reproduction is the production of progeny without the union of cells or nuclear material. Chlamydomonashas a life history that includes an asexual cycle (h-k; most cells are produced this way) and a sexual cycle. You need to be a group member to play the tournament It a haplont. In the haploid vegetative cells of the colony, the chloroplasts are arranged in spirals, containing darkened regions called pyrenoids where carbon fixation happens.
